PUMP.

Application filed August 20, 1924. Serial No. 733,156.

To all whom it may concern.

Be it known that I, JACOB W. BIRD, acitizen of the United States, residing at WVoodland, in the county of Yolo and State of California, have invented new and useful Improvements in Pumps, of which the following is a specification.

My present invention has reference to a water elevating means'in the nature of a pump provided with any desired number of cylinders connected with the barrel of the pump and arranged for reciprocation in each of the cylinders there is a sucker valve, each of the said cylinders having its bottom provided with an inwardly opening valve, while means is also provided for imparting a timed reciprocatory movement to the several sucker valves and whereby a larger quantity of water can be elevated with the same amount of power required in the operation of an ordinary single action pump.

T o the attainment of the foregoing and other objects which will present themselves as the nature of the invention is better understood, reference is to be had to the drawings which accompany and which form part of this application.

In the drawings Figure 1 is a side elevation of the upper portion of a pump constructed in accordance with this invention.

Figure 2 is a sectional view onthe line 2-2 of Figure 1.

Figure 3 is a view looking at right angles to that disclosed in Figure 1.

Figure 4 is a side. elevation of the casting comprising a portion of the pump barrel and to which the cylinders are connected.

Figure 5 is a sectional view approximately on the line 5-5 of Figure 6.

Figure 6 is a sectional view approximately 0n the line 6-6 of Figure 4.

Figure 7 is a sectional view on the line 7--7 of Figure 5.

On a suitable base or platform 1 on the ground surface of a well I secure or form a frame structure. The frame includes spaced uprights 2, connected with an end plate 3 from which arise spaced standards 4. The upper end of each of the standards is provided with a bearing. forthe straight ends of a cranked shaft 5. The cranks of the shaft are disposed at rightangles with respect to each other and four of these cranks, indicated by the numeral 6, are employed. To each of the cranks 6 there is secured a pitman. 7, each of the pitmans, turn, being pivotally secured to the bifurcated upper end of a plunger rod 9. The rods pass through suitable guide tubes 10between the base 1 and the plate 3- of the frame.

Journaled in suitable bearings 11 on the upright 2 of the frame there is a shaft 12.

On. one end of the shaft there is a pulley wheel 18, and on the second end there is a pinion 14. The pinion is in mesh with a gear wheel 15 that is fixed on one of the straight outer ends of the shaft 5. The diameter of the gear 15 is comparatively great with respect to the diameter of the pinion 14. n

The barrel 16, of the pump asses through the base of the frame an also through a central opening 17 between. the uprights 2. The port 17 communicates with a transverse passage 18 preferably integrally formed on the frame and the outer end of the passage is threaded, as at 19, whereby a conductor pipe may be screwedtherein.

The barrel 16 is screwed in the upper end of a casting 20. The casting has a central bore 21 that communicates with the barrel 16. The casting is of a peculiar formation, having its sides provided with rightangular flanges 22 and to each of these flanges there are bolted cars 23 formed on the inner face of cylinders 24. Each cylinder has a port 25 that registers with a similar port in the bore 21 of the casting 20. The cylinders have their upper and closed ends provided with outstandin hollow bosses which are threaded and which have screwed thereon packing nuts 27, Each of the cylinders receives therein one of the severalrods 9, and on the end of each of the rods received in the respective cylinders there is an inwardly opening sucker valve 28. Each of the cylinders 24 has its lower end opened and screwed in the said end there is a seat 29 for an inwardly opening valve 30.

By reference to Figure 7 of the drawings it will be seen that the sucker rods 9 are guided between the flanges of the casting 20.

Incident to the rightangular arrangement of the cranks 6 on the shaft 5 it will be noted that when the shaft 12 is turned a timed reciprocation of the sucker valves 28 in their respective cylinders 24 will be produced so that a continuous flow of water or other fluid will be elevated through the bore 21 of the casting 20 and. the, barrel 16 and ejected through the outlet 18. From experi once it has been found that my improved nin'iping apparatus may be operated at a cost not exceeding that of the operation of an ordinary single action pump while four times the quantity of Water delivered by a single action pump is elevated by my improvement. The structure is comparatively simple and its advantages, will, it thought be apparent from the foregoing); description.

Having described the invention 1 claim A multiplex action pump including; a frame, a barrel connected to the frame and having an angle outlet, a casting; having; a central bore secured to the lower end of the barrel superimposed anpiularl related cylinders connected to the casting); and having; ports communicating with the bores thereof a gravity influenced inwardly opening "valve at the lower end of each cylinder providing a fluid inlet thereto, a sucker valve in each cylinden a rod connected to each snclzer Valve and extending thron'yh the cylinder and guided throngli the ne a pinion on the frame. a toothed n'heel jonrnaled on the frame and inter-meshing with the pinion a crank shai't For the toothed Wheel. the cranked portions ot' the said shafts being rightangrnlarly related a pitnian connected to each of the cranked portions oil the sl "ft and likewise connected with the rosy/er rods, guide means on the frame for the rods and means for revolving" the pinion.

In testimony whereof I affix my sigognatnre.

JACOB BIRD.
